minations of rod 8 by means of sleeves that embrace the rod, and brackets connected with the sleeves by vertical pivots;the=result being that the beams may swing freely in any direction but may not turn on theirlongitudinal axes. Rods 1O connect with the beam preferably through racks, as 2% in Fig. 2-3, which givdifierent poin of connection, and they are bent to form the loops 11, which pro- ;vide hand-holds for the operator, and nen- 6o tralize the jar incident to throwing the parts into position to'hold the beams raised from the ground.- Brackets 17 are secured on the upper part of the arched axle adjacent to the hounds. They are grooved, as shown atZO in Fi 3,tolrhove lengthwise of the spline 21, ,showri in. Fig.5, which spline is formed on a fixed-saddle that restson' the axle, and they are secured in position on the axle by means manner. Each bracket has a rearwa'rd fork 'l8, tl 1e fingers of .which diverge, and a forward extension 19 which provides a point of connection for the hook-bolt 22.

Rock-levers 12 are pivoted at their'lower 5 code between lugs of the brackets, and each has at itsfupperend a forward extended book 13 and a rearward extended eye 14. The rods 10 connect with the eyes offthe rock-levers, and the compound springs, 15 and 16 8o connect with the hooksof the lovers and with the hook-bolts of the brackets. The spring 15 is, an ordinary coiled expansion spring having nearly, or quite, sufficient el-astic tension' to counterbalance the weight of the cultivator beam when vthe same is in operation, and more than enough to sustain it when it israised, and when the leverage is shifted in favor of the spring. The spring 16 is a comparatively stiff spring, much shorter than spring 15. It is connected at one end with hook-bolt 22 and at the other end with thread ed rod 16". The. threaded rod acts [in turn-. buckle '16", and link 16 connectsthe turn= buckle with the hook of the rock-lever. matter of convenience, and to improve and simplify the appearance of the device, the spring 16 is placed inside of spring 15, and its function is to act against the foot pressure of fof bolts-and clips, or in any other desirable 7o Asa 5 the operator, on stirrups 23, and facilitate the ice governing of .the depth of cultivation. To

adjusted until the spring (16) and its difierent adjuncts are long enough to permit the beam to assume, or nearly assume, its operative, cultivating position before tension 1s exerted on the spring; and then when unusual pressure is temporarily applied by the footof the operator on the stirrup of the beam, either'inadvertently or to follow a depression, the stiff, strong spring will act promptly to return the beam to its normal position as soon as the pressure is relaxed. If the said spring is put under slight tension just before the beam is depressed to its normal position, and uniform pressure on the stirrup is used to neutralize such tension the beam may be raised slightly to meet an occasional requirement by simply reducingthe pressure on the stirrup.

In operation the beams are connected with rod 8 the desired distance apart, and the brackets are adjusted lengthwise of the axle to correspond with such connections. One end of the seat strap is lifted from the pin'of the collar and swung rearward to admit the operator, who replaces the strap and seats himself with his feet in the ,stirrups. The rods 10, which up to this time have been occopying the position indicated by broken lines in Fig. 3, are grasped by the loops 11 and the levers are rocked, against the tension of springs 15, until the beams are in operative positions and the connectionsrof springs 16 are stretched, before explained. The cultivating then proceeds as specified until an end of the field is reached when the foot pressure on the stirrups is removed. The rods are given a preliminary lift bygrasping the loops 11 and the springs 15 carry the levers over their pivots, raising the beams andthe cultivating shovels thereon to the'positionsoriginallyoccupied. Astheleversswing over their pivots the rods pass between the fingers of the forks and are guided thereby to their resting places in the crotches, wherethey hold the beams against horizontal swing. The levers Swing over with some force, causing the rods to strike the brackets sharply, and the spring, or cushion, formed by loops 11 enable the rods to stand the jarwithout becoming permanently bent. The loops also make the rods somewhat elastic, longitudinally, and increase the facility with which the beams may be controlled.

To suit different drivers it is necessary to have the seat adjustable with relation to the stirrups, and this is effected in a simple and practical manner by means of the sliding collars with their pins for the seat strap and the soon ring set-screws.

The springs 15 and 16, while connected in construction, are entirely distinct in operation and perform their respective functions at different times. The spring 15 acts only to raise the beams, or assist therein, and to hold them raised, and for this purpose a comparatively weak spring capable of considerable expansion is desirable. On the other hand-the springs 16 have nothing to do with raising the beams, are not under tension while the raising is performed, and their function requires that they be qnick-acting and strong. The different springswould operate one beside the other instead of one in the other, but,

for the reasons heretofore given, the latter arrangement is very much preferred.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. In a cultivator of the class described, and in combination with the essential elements thereof, springs tending to lift the cultivating shovels clear of the ground, and-other springs adapted to act against foot pressure when the shovels are in operative positions, substantially as set forth.

2. In a cultivator ot'the class described, the combination of cultivator beams, rock-levers pivoted above the beams,lin ks connecting the swinging ends of the rock-levers with the beams, springs tending to lift the beams and shovels thereof clear of the ground, such springs being connected with thelevers, and

other springs also connected with the levers and adapted to act against foot pressure when the shovels are in operative positions, substantially as set forth.

3. In a cultivator of the class described, the combination of a frame,one element of which 7 is an arched axle, brackets-mounted on the arched part of the axle, rock levers pivoted at their lower ends in the bracket in a manner to permit their upper ends to swing back and forthover the pivots, links connecting with the beams of the cultivator and with the upper ends of the levers, and springs also con nectingwith the upper ends ofthe' levers and with forward extensions of the brackets, whereby the upper ends of the levers, of the links and of the springs may all be swung over the pivots of the levers and hold the beams raised by bringing the points of support into substantial alignment.

4. 1n cultivators,the combination of the beams, the rock-levers, and the links looped between their ends to form hand-holds and increase the elasticity of the links, substantially as set forth.

5. A compound spring for riding cultivators. the same comprising the outer spring 15, the inner spring 16, the threaded rod 16, the turn-buckle 16", and the link 16, substantially as set forth.

In testimony whereof we sign our names in the presence of two subscribing witnesses.
